I was going to write about the AQA exam paper today, but decided to push ahead with it yesterday because people were asking to see the paper. As such I’ve only got a little “bonus” link on offer for you this morning: the MegaPenny Project.

People often have difficult wrestling with big numbers like a million or a billion. It’s very hard to picture a billion of anything, but billions and even trillions are tossed around the news all the time these days. I found the MegaPenny Project a number of years ago, and it’s really great for visualing these types of large numbers. Starting with a single US penny the site builds to a massive quntillion, 1 followed by 18 zeros, in pennies by using handy comparisons like a person, a school bus, or the Empire State Building. A bit more than a small chunk of change then.
